Reported treatment adherence rates of patients with end stage renal disease (ESRD) have been extremely varied due to lack of reliable and valid measurement tools. This study was conducted to develop and test an instrument to measure treatment adherence to hemodialysis (HD) attendance, medications, fluid restrictions, and diet prescription among patients with ESRD. This article describes the methodological approach used to develop and test the psychometric properties (such as reliability and validity) of the 46-item ESRD-Adherence Questionnaire (ESRD-AQ) in a cohort of patients receiving maintenance HD at dialysis centers in Los Angeles County. The ESRD-AQ is the first self-report instrument to address all components of adherence behaviors of patients with ESRD. The findings support that the instrument is reliable and valid, and is easy to administer. Future studies are needed in a larger sample to determine whether additional modifications are needed.
This study was conducted to develop and psychometrically test an instrument designed to measure adherence behaviors of patients with end stage renal disease (ESRD) receiving maintenance hemodialysis (HD) at dialysis centers in Los Angeles County. Maintenance HD is the most common renal replacement therapy (RRT) for the many individuals who suffer from ESRD (United States Renal Data System [USRDS], 2009). When RRT is initiated, patients' lives change completely. Patients requiring in-center HD must regularly travel to a dialysis center, consistently take prescribed medications, and extensively modify their diets. Successful treatment of ESRD depends largely on patients adhering to their very demanding recommended treatment regimens. Despite the importance of adherence, which is defined as following medical or health advice (Denhaerynck et al., 2007), many patients with ESRD who are on HD fail to adhere to their recommended treatment regimens. Reports concerning adherence vary widely, and the non-adherence rates to attendance at HD, prescribed medications, fluid restrictions, and dietary intake range from 0% to 32.3%, 1.2% to 81%, 3.4% to 74%, and 1.2% to 82.4%, respectively (Bame, Petersen, & Wray, 1993; Bleyer et al., 1999; Block, Hulbert- Shearon, Levin, & Port, 1998; Durose, Holdsworth, Watson, & Przygrodzka,...
